Guys,
Please your input would be very much appreciated. I have a workstation in workgroup with user account for user in AD that's connecting to TMG proxy in Active Directory. All was working fine until one day system started acting up and use a old proxy setting. In IE options, it keep filling in old proxy settings. If you manually change to correct proxy, it works for few hours and plug in back old proxy settings. Edit registry with new settings then work for few hours then same problem. Auto config in not selected in IE options. Other users with workstation in workgroup are not have this issue, just this one. Please assist.
